Polyzole®

polyzole-filament

Polyzole®
Polyzole® is a thermo-resistant synthetic material. It is available in pulp, staple fiber, and filament form. Polyzole® does not melt and is available in two forms: UV stabilized & natural. Polyzole® has excellent “tribo” properties. Current applications include protective apparel, break pads and hot-gas filtration.
